Discovering proxy points
In the Lon Point Manager, all available point data are already discovered when the device was initially learned. If you added a DynamicDevice offline, and then referenced a specific Lon Xml file, the available point data are then known to the driver.
Prerequisites: You already discovered your devices.
This discovery procedure is basically the same for the local Lon device and dynamic devices.
Perform the following steps:
- Double-click the Lon network followed by double-clicking the points icon (
) under the Ext column for the device in question.The Lon Point Manager opens. - Click the Discover button or toggle learn mode on by clicking the Learn Mode tool (
) on the toolbar.
Under Target Name the driver lists all points by the names of the Lon components that are associated with the device. For example: nvEmerg and nvoUnitStatus. By default, the driver displays nvs and ncis variables as structured SNVTs (Standard Network Variable Types). That is why you only see the first data element in the structure with a + to the left of the nv or nci name.
- To expand and see all data items in the SNVT structure, click the +.Each item is a potential candidate for a Lon proxy point.
